No, this isn’t what happens when you’ve imbibed too much! It is the name of a dish whose origin is unclear; however, it is definitely British. There are so many theories about the name, but it probably has to do with the noises emitted while the cabbage is bubbling in the water and then squeaks in the skillet with the sausage. Bubble and squeak was popular during World War II as it was a good way to use leftovers during the time when most food was rationed.
With the addition of eggs, the Brits eat bubble and squeak for breakfast as well as dinner. It sounds great to me and a meal perfect for any time. Bubble and squeak does not take a lot of effort, and it's high on goodness!
